We’re taking it back to the streets of San Francisco. Ah yes, the lyon st. steps or stairs, whatever you want to call it, we’re doing it outside. Rain or shine, this cardio specific interval group class will keep your legs moving and heart pumping! Meet you up at the top of Broadway in the Marina.

Ever wonder how hard you're actually working out in the gym or during outdoor bootcamps? Most of us measure our intensity from the amount of weight we lift, reps we perform, sets we complete, respirations we take or even the sweat we perspire. Now, with our group exercise classes in the city, you're visually able to see how intense the workout actually is, wearing a heart rate monitor. Prior to the first training session, we find the right target training zone for you (burning the most fat) and get the best out of your group workout! Following the best training session in San Francisco, the amount calories burned is then analyzed and shared to everybody (which is pretty cool). Jump-in on the best group class, located in the Marina of San Francisco, to get in best shape and see what's up (your heart rate)!

This short fitness video displays outdoor bootcamp workout examples including core training.
